Interface Connections
This section provides the pin number assignment and wiring information for the connectors on the
ExtendAir G2 24GHz radios. All connectors are shown as viewed from the radio front panel.
RSL Connector
A female BNC connector is provided on the radio chassis. This connector can be used during the
antenna alignment process, to provide a received signal level (RSL) voltage to a voltmeter.
Power/Ethernet Connector
This connector is the primary connector on the radio, and must be connected to provide power to the
radio, and primary Ethernet communications for traffic and Ethernet. Figure 45 illustrates the pin
orientation and functionality for this connector.
Use a straight cable (wired as a standard Ethernet connection) for connection between the Power
Injector and the PoE port of the radio. The wiring follows the 802.3at standard for Power-over-
Ethernet (PoE).
Figure 41 Power/Ethernet connector
Note: Wire the CAT5e/CAT6 cable for the PoE connection as a ‘straight-through’ cable
between the PoE injector and the radio. The cable connected to the injector for network
access may be either straight-through or cross-connected. The secondary Ethernet connection
may be wired as straight-through or cross-connected and does not have power applied.
